T o all whom t 'mayConcern.'y n Be it knownthat I, HonAToiG. GVILLMon, a citizen ofthe United States, residing at IVashington, in the District of Columbia, have invented certain :new anduseful Im-y provements in Anticreepers,"oiwhich the following is a specification;

vMy invention relates to devices Ator preventing the longitudinal creep of railroad rails, such devices being-commonly known asanticreepers, rail anchors, creep-checks' or rail stays.

The principal object of the invention is to provide a device o'l' this type which will be simple in its construction, inexpensivetoV manufactura l light `in weight, strong and capable of taking'a lfirm fand reliable hold on the rail, which` willnotbe aiiectedrby vibration, movement of the railteinporarily .in a direction the reverse of that in which the rail tends tor creep or any other cause tending to loosen the grip of anticreepers on the rails engaged thereby.`

A: `further Objectis to providefav'device constructed in onefpiece whichl may be quickly and conveniently applied to the rail with Ithe tools usually employed by track The device possesse'sfother features of novelty and advantage,` which, with the foregoing, will be obvious from the followparts in the several figures ofthe drawings.

In the embodiment of the invention illus- .tra'ted in the drawings the rail A rests upon crossties, a portion of one ofwhich is shown and indicated by B, and is ofthe usual construction with a head C and a base D. 'Ihe anticreeperE is constructed withVK a surface F adapted to engage the under portion of the'rail head GandV a suraceG adapted to .engage the upper'surface of-the rail base D at one side ofthe rail A, anda surface I-I adapted to engage theedge ofthe rail base at the lother side the rail A. lThe Vportion ILofthe anticreeper E,Vupon which are the surfaces `Gr `and F, is Iadapted to beforced into the ishingspacebetween the' head C `and baseD ofthe rail vA andthe portion-K of the anticree'per upon which isthe surface is adapted V'to be positionedoutside' the" base D of the rail Aopposite the por, tion I. The upper freefen'ds of the'portions I and"K of' the anticreeperE Whichfare substantiallyparallel to each other, are con,-l

nected the one to the other by rcurved lporftions L and M anda `straighttransverse portion'N, Aeither of thefaces OorPQof which is "adapted to engage with thelcrosstie Br .The portion K,`the curved portions L and M and Jthe transverse portion N are so formed vandf relatedfto each" other as to permit the Vanticreeper E.V to receive' the rail base D between the curved portion L and the portion Kl `and allow the end R of the portion K to lbebroughtabove the rail', base `D vand also toreceivefthe rail base D between the curved portion M,l`withfthe end R 'of lthe portion Khabove'therail'base D, and the vsurface G oftlieanticreeper E.'

Several blows of a hammer or similarimplement may benecessary and the force so applied will kproduce angular movementvof the anticreeper E in rela- ;tion' to the rail A with the surface H of the portion surface F of the portion I riding onthe opposite surface. of the rail head Gand p the surface Gpivoting or fulcrumiiig on the corner of the rail base D. Force is applied inthe manner described until the angularl movement of. the anticreeper E 'brings the surface Gr intofull Contact with the upperv surface of the rail base D at which time (see Figure-1) the fiat portion of the sur- F is in full contact with the under surface' of the railhead C at lone side ofthe railV A and fthe surface o I-I of the portion l .K vof tlievanticreeper E is in V:tulleontact with a,1i.dfwillM press laterally upon the vertical edgel of the rail'basey D at theother side of the rail'A. Onefor more `blowsfupon the portion I of the anticreepery E toward the rail `at about mid-height of the yfishing space oithe rail'A will ordinarily be sufficient to' firmly wedge the portion I of the anti- Creeper E in the fishing space between the head C and baseD ofthe 'ra`ilr' Av."V

""It Vwill :readily be seen that'. .in this final 4operative `position the antiereeper `E firmly grips the raily A, the portion-'I being wedged lin to the fishing space betwet'eii the head Cv and'lbase D ofthe rail and pressing firmly against itV atk oneI side,l while the portion -K .presses firmly against they edge of c theV rail base D attlie other sidev of thefrailgfand that it is' efi'ectually llocked upon thefrail by *the position of theportionIv of the anticreeper E andtheengagement Yof its .surfaces F and G .with the` head Candbase D of the rail A. i

A :The direction in`4 which they rail tends to creepv isindicated by the arrow in Figure .2.

Contact of the gface O1 with 'the crosstie'B lprevents forwardv movementl of the` lower portions L, Mia-nd Nk of the anticreeper`E K riding on one rail edge, theV ybase D ofl the rail. rIhe gripping action of the anticreeper Eiipon the rail A will thus be increased by and in proportion to the creeping tendency. other cside of the rail A as illustrated by Vh'enit ,isv desired to kremove the anticreepe'rzE from the, rail A this may be done by Vinserting a wedge between the upper Y,

portion-V of the portion I and driving the wedge longitudinally rofthe rail to force the surface F outwardly from the rail and outof engagement with the rail hea-d C. Theanticreeper E 'will' thus be caused to move angularly in a plane Vtransverse to the rail'with the surface II of the portion I( riding upward on the rail base edge until the position shown in Figure 4 is reached, after which,lwiththe rail base D loosely embraced :by the antiereeper E, it maybe inclined fromthevertical and'move transversely ofk therail outofcontact therewith.

This inventionin its broadest aspect,re lating to the ytype of anticreeper herein disclosed that locks on the rail' by vengagement withthe head and baseV aty one side of the rail andthefedge of the .base of vthe rail :it

its other side isnot claimed'hereim but will befound'claimed in my cti-'pending applica- Y tion, Serial No. 722,317, filed June 25, 1924.

Q'While'gIhave described one embodiment of my,` invention, modifications might be made without .departing fromi'the prinyciples: oflthe invention.

5. An anticreeper comprising a body, and end arms formed integrally with said body and in the same plane therewith and having approximately parallel terminal portions adapted to have direct engagement with the head and base at one side and with the base at the other side of a rail, the arrangement being such that with one arm entered in the space between the head and base at one side the other arm is free to ride onthe rail base to al position of surface engagement with the vertical edge thereof, and that when said arm is brought into its full operative engagement with the rail base on its side and said arm first named is forced in between the head and base of the rail on the vother side, said body is stressed.

6. In an anticreeper a straight body adapted to bear against a crosstie, disposed so as to be out of contact with the bottom of the rail base, and approximately parallel end portions disposed so as to rigidly engage the under side of the head and upper side of the base at one side of the rail and to have surface engagement with the edge of the rail base at the other side of the rail, when said body is forcibly movedy angularly transversely of the rail, and thereby lock said anticreeper in position on the rail.

7.
